Paper Abstract

On-line phase shifting digital holography requires recording of multiple holograms. In this paper, we describe a real time 3-D object recognition system using single exposure on-line digital holography. In contrast to 3-D object recognition employing conventional phase shifting scheme which requires multiple exposures, this method requires only one single digital hologram to be synthesized and used to recognize 3-D objects. A benefit of the proposed 3-D recognition method is enhanced practicality of digital holography for 3-D recognition in terms of its simplicity and more robustness to external scene parameters such as moving targets and environmental noise factors. We show experimentally, that the single exposure on-line digital holography based 3-D object recognition method is capable of providing 3-D object recognition. The experimental results are compared with that of the on-line phase shifting digital holographic based 3D recognition.
